2. 1. Towards QoE-aware mobile infrastructures : QoE-based Resource Management in Mobile Networks

   Author : Luis Guillermo Martinez Ballesteros; Zary Segall; Anders Furuskär; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Quality of Experience; Radio Resource management; Mobile Networks; Informations- och kommunikationsteknik; Information and Communication Technology;

   Abstract : With the development of mobile networks, customer needs and behaviourshave changed. Mobile communications means so much more than simplevoice communication; there is now mobile Internet with web surfing, videophone,streaming media, and micro blogging. READ MORE

4. 2. Exploiting Energy Awareness in Mobile Communication

   Author : Ekhiotz Jon Vergara Alonso; Simin Nadjm-Tehrani; Daniele Puccinelli; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wireless transmission energy; energy consumption; mobile devices; power measurements; application energy; data pattern; trace-based simulation;

   Abstract : Although evolving mobile technologies bring millions of users closer to the vision of information anywhere-anytime, device battery depletions hamper the quality of experience to a great extent. The massive explosion of mobile applications with the ensuing data exchange over the cellular infrastructure is not only a blessing to the mobile user, but also has a price in terms of rapid discharge of the device battery.
